The Nintendo Japan site disclosed the official specs on the 3DS, and while overall it looks good, there is one thing that might be a deal breaker for some. Apparently, it takes a whole lot of battery life to power a 3D screen, even one the size of the 3DS.
It appears that the 3DS may have a bit of a battery issue. According to the specifications on the Nintendo Japan website, when playing cartridge games you can expect a battery life of 3.5 hours. It’ll also take 3.5 hours to recharge the device. Battery life does improve if you use software instead of cartridges, but it may take some time before there’s software in the store that supports the 3D functionality. So the real question is will the battery life be an issue for you? Or do you still want to buy a 3DS?
